本発明は超電導回転電機の固定子や回転子の巻線支持装
置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a winding support device for a stator or rotor of a superconducting rotating electric machine.
一般に鉄心に溝加工して楔で巻線を支持固定する手段は
糸縛りなどの方法に比べ、強固な支持固定ができる。し

導発電機の回転子の巻線端部には最大電磁力が働くため
、この部分を強固に支持固定するために絶縁物のブロッ
クを巻線間の空隙に挿入して固定する手段がある。In general, means for supporting and fixing the windings by cutting grooves into the core and using wedges can provide stronger support and fixation than methods such as string tying. However, in rotating electric machines that operate in high magnetic fields, such as the stators and rotors of superconducting generators, iron cores cannot be used because the iron loss becomes too large. In addition, for example, since the maximum electromagnetic force acts on the end of the windings of the rotor of a superconducting generator, in order to firmly support and fix this part, there is a method of inserting an insulating block into the gap between the windings and fixing it. There is.
しかし、−Ｊ−記手段は、絶縁物の形状を巻線に合せて
、固定に緩みが無いようにすることが必要であるため、
巻線の曲線部分に装填する絶縁物の形状が曲線状に複雑

織った織布を重ねたものであるので、層剥れが生じ易い
という問題があった。However, in the method described in -J-, it is necessary to match the shape of the insulator to the winding to ensure that there is no looseness in fixing it.
There was a problem in that the shape of the insulator loaded into the curved portion of the winding became complicated. In addition, conventional insulators have been made of fiber-reinforced plastic (hereinafter referred to as FRP), which is made of insulating fibers such as glass fibers, but this is made by layering two-dimensionally woven fabrics. However, there was a problem in that layer peeling was likely to occur.
本発明の目的は鉄損のない、簡単にして、強固で信頼性
の高い超電導回転電機の巻線支持装置を堤供することに
ある。An object of the present invention is to provide a winding support device for a superconducting rotating electric machine that is simple, strong, and highly reliable and has no iron loss.
鉄損を生じない簡単にして強固な巻線支持装置とするた
め、本発明では構造材として絶縁繊維の３次元織物を基
材としたＦＲＰを用いる。In order to provide a simple and strong winding support device that does not cause core loss, the present invention uses FRP having a three-dimensional woven fabric of insulating fibers as a base material as a structural material.
このようにＦＲＰを用いるのは、鉄損を生じないこと、
また基材を３次元織物としたことにより機械的強度が極
めて高いことによる。The reason why FRP is used in this way is that it does not cause iron loss.
Furthermore, since the base material is a three-dimensional fabric, the mechanical strength is extremely high.
実施例１ 以下、本発明の第１の実施例について説明する。 Example 1 A first embodiment of the present invention will be described below.

ａ！０）により巻線を支持固定する。This shows the stator side of a superconducting rotating electric machine. That is, as shown in the cross section in Fig. 1, after cutting grooves (2) to match the shape of the winding to be housed in FRP (1) in which glass fibers are arranged three-dimensionally as insulating fibers, the winding is ■A! is attached to the groove (2), and then a! is made of FRP or non-magnetic metal. 0) to support and fix the winding.

角部（ｌａ）。Next, the operation of this first embodiment will be described. In order to form a strong support device for the winding (3), it is preferable to use long fibers, and it is better to use fibers arranged in three dimensions rather than one or two dimensions. The mechanical strength may also be increased. When woven fabrics are laminated, cracks and layer peeling are likely to occur between the woven fabrics. In particular, the corner (la) of the FRP shown in FIG.

る。Stress is concentrated in (lb), (lc), (], and d) during cutting and operation, and cracks and layer peeling are likely to occur in these. Furthermore, when large-sized FRPa materials are applied to equipment that operates at extremely low temperatures, such as superconducting rotating electric machines, cracks, layer peeling, etc. are more likely to occur due to heat storage. Cracks, layer peeling, etc. are undesirable because they significantly reduce the mechanical strength of FRP. Therefore, we stacked woven fabrics and passed the fibers through them in a direction perpendicular to the surface of the woven fabrics.
Dimensional fabrics can avoid these problems.
